CAR-WHEEL.

SPECIFICATION forming pere of Letters Patent No. 257,625, dated Mey e,lese.

Application filed December 24, 188i.

To all whom it may concern:

- Be it known that I, FRANCIS M. TANEYHILI., a citizen of the UnitedStates, residing at Barnesville, in the county of Belmont and StateofOhio, have invented new and useful Improvements'in the Hubs ot' Coal0arWheels and intheOil-Boxes to Coal-Gar Wheels, of which the following isa specification.

My invention relates to improvements in can wheels; and itconsistsindetailsofconstruclion and arrangement of Ithe several parts that will behereinalter more fully set forth in the specilication and claim, andpointed out in the accompanying drawings, in which- Figure] is a sectionof a car-wheel embodyling my improvements; Fig. 2, a section on line wFig. l; Fig. 3, a section of sameon line b b, Fig. 4, and Fig. 4is aside view ofthe wheel.

Like letters of reference rct'er to like parts in the several gures. i

Referring more particularly to the drawings, c represents those parts ofthe solid hub between the-wcdge-shaped openings d, through andlengthwise the solid hub, by means of which the oil is enabled lo passto the axle, and said openings also serve to hold, lift, and distributethe oil as the wheel revolves.

c represents those parts of the solid hub at the posterior ends ot' theopenings d, and are sloped back from the ends ot' said openings.

At the inside end of the oil-box are the posterior bars, j', which actto produce checks or eddies and currents in `the oil as the wheelrevolves, and also prevent the oil from smearing on the rim and ends ot'the oil-box', thereby forcing oil to the points oflubrication.

(Model.)

The oil-box is provided with an oil chamber or recess, G, in its outerrim, and has an opening, H, to the outside end ot' said oil-chamber.Through this opening H the oil box maybe lled full of oil withoutaffecting the tightness of the oil-box, thereby increasing the period oflubrication. This opening H is hermetically closed by a screw plug andcap, K, secured in place `by screws and .taps L m. By means of cap K theoil is prevented from wasting, and dust and other foreign substancesexcluded from the oil-box. n The axle N is b v this construction ofwheel kept constantly lubricated with pure oil and wastage prevented.

I am awarethathubs to coal-car wheelsha've been so constructed as toletthe oil to the axle, and that they have been ina-de with unbrokensurfaces on ltheinside ot' the rim and ends ot' the oil-box and placedbetween the hub and V inside ends ofthe spokes of the wher-ls. Suchconstruction I do not claim; but

I do claim- In a car-wheel provided with a recessed oilbox,thecombination ot' the barsf ou the insideofsaid oil-box, a hub having`wedge-shaped openings el for the passage ot' the oil to the axle, thesolid ends c sloping back from the ends of the oil-openings, and aremovable cap, K, hermetically secured to the outer end ot the oil-box,substantially as shown and described, and for the purpose set forth.
